@drtaraswart: Both of these exercises can help us to quickly regain control from feelings of stress or anxiety. Physiological Sigh 😮‍💨 - By mindfully sighing a few times, you can manually reduce two key symptoms of stress within a few seconds. Inhaling twice causes the collapsed alveoli to reinflate with air. As a result, the surface area of the lungs increases and CO2 is removed from the body much more efficiently. This makes the body feel more relaxed. Long exhales cause a slight increase in pressure to the receptors in the heart. This sends signals to the brain to slow down the heart rate which creates a relaxed feeling. Half Salamader 🦎 - This vagus nerve exercise shifts your nervous system out of 'fight or flight' and into 'rest and digest'. The vagus nerve is a cranial nerve that controls our autonomic nervous system. This is the part of our nervous system that helps regulate our homeostasis (a state of balance within our body). Did you try either of these exercises? How did they feel? #nervoussystem #neuroscience #nervoussystemregulation
